Population over time

2 figures

Corwin grew from 421 to 484 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

The History of Warren County, Ohio, published 1882 names this settlement in its chapter on Wayne Township. These are the passages that mention it, exactly as the scans read.

Before 1819, the channel of the river on the road to Corwin was not as now, but where the bridge now is was in the bend of a horseshoe, the channel above and below the bridge having been made since. The crossing of the river was between High and Main streets, in Waynesville. When the water was high, there was a ferry used, and when low, a ford. About 1812, an effort was made to build a bridge at the ford. The abutments were raised and a superstructure was placed on trestles. A freshet in the river swept out the work and no further effort was made to build a bridge at that place. In 1817, a bridge was built on a contract, where the bridge now is, by John Satterthwaite, for $700, including the abutments. It was built of oak timber, principally hewed, never covered or weather-boarded, and only lasted about ten years. At that time, the road crossed the West Branch of the Miami, known as the race at the mouth and followed the north bank of the Miami to the bridge. The race wsa then a small stream, no bridge over it; the ford was a very bad crossing.

In 1840 or 1841, some Virginians were moving through to Missouri with their slaves. It was claimed by slave-owners that they had a right to cross the State with their slaves for the purpose of business, or removal, when their destination was another Slave State. This was denied by the anti -slavery people of Ohio. A warrant was sworn out before Jonathan Clark, a Justice of the Peace here, by Dr. Brooks, and the slave-owners were arrested between this place and Franklin, and brought back and tried here. Judge George J. Smith and Robert G. Corwin were counsel for the prosecution, and Charles Anderson, of Dayton, for the defendants. After hearing the case, Squire Clark discharged the defendants. Some persons about Springboro and vicinity spirited away the slaves, or a part of them; they were afterward indicted by the grand jury, and tried, I believe, before Judge Hinkson in the Warren County Court of Common Pleas, convicted and sentenced to fine and imprisonment in the dungeon. The Supreme Court was in session at Cincinnati, a writ of error obtained therefrom, and the defendants were released from imprisonment. The case finally came before the Supreme Court of the State, when the question was set tied definitely, as claimed by the anti -slavery party.

In a pretty early day, CoL John McDannell, who had been a Colonel in the Revolutionary war, and who possessed all the hauteur of a gentleman of the olden time," came from Dauphin County, Penn., with his family, and set tied on the farm now owned by D. F. Corwin. They came all the way in a carriage, which was probably the first carriage ever brought into the township, if not the first in the county, and had a negro driver.
